SEOUL - Fans of the 2011 K-drama Dream High will know singer-actress Suzy, who played the student who stole the heart of Kim Soo Hyun's character in the drama.
Suzy has been revealed to be dating heart-throb Lee Min Ho, 27, in news that trended on Monday on Twitter and Facebook worldwide.
Both confirmed that they have been dating for about a month, with Lee's agency saying the pair are "carefully building the relationship".
Sparks could have started flying in January, going by a timeline of the sightings of them together.
On Jan 20, she was at the VIP preview of Lee's film, Gangnam Blues, in Seoul, perhaps at his personal invitation.
It marked his first lead role in a feature film. Suzy, 20, is a popular member of K-pop gal quartet Miss A and a K-pop sweetheart with movie awards under her belt.
The day after, she lent her support for Gangnam Blues, posting a picture of herself at the premiere on Instagram and saying she hoped it would make big money.
The two were then sighted on Feb 17 at a restaurant in Seoul. On Feb 25, he was seen taking her out on a car ride around Itaewon and Namsan in Seoul.
On March 10, reports say, they left Seoul separately - he to Paris for a shoot and she to London.
Five days later, he was spotted in London with his mother, sister and brother-in-law.
He was also seen picking Suzy up in a chauffeured Mercedes and proceeding to the Shangri-La Hotel at London's tallest building, The Shard.
They entered the hotel one after the other, with Lee pictured hiding his face with a scarf.
They left London separately after spending a three-day, two-night holiday together, it was reported.
South Korean website Dispatch, which broke the news of their relationship, said they had been inseparable since Feb 23, spending almost every day together.
News of the budding romance has come as a surprise as they have not worked together before.
Both have been linked to other stars previously.
Lee had admitted dating Park Min Young, his co-star in 2011 drama City Hunter, but they broke up after several months.
In 2011, Suzy denied talk that she was dating Kim. She also denied dating Sung Joon, her co-star in 2013's Gu Family Book, after they were photographed together.
Was the London trip also a planned opportunity for Suzy to meet Lee's family?
If so, will things turn serious for them? Fans can only speculate.
